😂 yeah tortoises probably didnt receive birth certificates then and werent that documented as modern zoo tortoises. In 1876 the german government started to do birth register and birth certificates, before it was churche's duty and pretty common even. In other countries it may have been in other times or not common at all and surely some people "fell through the cracks" and did not recieve one here as well.

>even the oldest humans alive today are "unverified" because they predate birth certificates.

I must object xD Birth documents are very old, in the "dark ages" churches eg had birth and death registers for the local population. And noble people always did care for their birthdate. And they weren't the first in ancient Rome birthdays (at least of important families) were registered, they had a calender and even wrote their own family history/tree (with some gods mixed in way back lol). Some of the oldest humans may have lost their certificate over time or were born in a place/time where noone cared for one for them or it gets unreadable etc. But we have many "oldest" humans verified by their birth certificate/ID/an equivalent of it, and registering birthdates and deathdates or at least times (month/year) is very old culturally.

I have no idea in detail but: Handsomeness oftentimes is traits which say you are healthy. Eg not being starving-thin nor unhealthy obese, having nice hair and skin (enough nutrients eaten), having a youthful look (the younger you are the less likely you get ill and the better you are fit for reproducing (more so as a woman)), having a good body posture and normal body features (again, nutrients and maybe even genetical disadvantages of anatomic stuff), red cheeks meaning you are young and not ill, nice eyes again if eyes are yellowish you may be ill/malnourished... So almost everything we call handsome is a sign of healthiness and fitness. There are much more factors.

I dont know if handsome people are healthier, I doubt it as many illnesses are coincidences/mutations or due to life circumstances. But I guess you can say people who are seen as beautiful almost never have visible health-flaws such as genetic disorders or other (genetic and visible) disabilties. Evolution made us find healthy people beautiful. And young people also. Simply because thats the best way to be sure to reproduce and have your genetic material live on.
